HEEL-XVASHEB-STAGKING MACHINE.

- Application filed August 7, 1924-. Serial No. 730,583.

. My invention relates to the art of manufacturing ruhher heels, and it has rticclar reference to a machine adapted to arrange a plurality of washers in regular relation so as to facilitate theirsuhsequent delivery to the pins of heel molds.

One object of my invention is to provide a device that will rapidly and accurately select and arrange washers in nested relation in superposed or such form that they may thereafter be conveniently placed on the ,mo dpins of molds for rubber heels and the like.

Various other objects and he derived from practicing my invention will be apparent from the accompanying specification and drawing in which:

Fig. l is a diagrammatic vertical sectional view of the machine, shown partially in clevation;

Fig. 2 is a view of the section of a selectorplate taken substantially on line 2-2 of Flg Fig. 3 is a lateral sectional view taken substantially on the line 23-43 of Pig. 1; and

Fig. e is a front elevational view of the top portions of the stringing wires. My machine is built upon the principle that, it small circular discs, such as heel washers are spilled on and caused to slide over an inclined plate member having indentures of proper shape and size, certain of the washers will he received in the indentures. It the plate .mcmhcr he tilted or inclined heyond' the anglev oi repose ol' the washers on the plate memhcr. those washers that are not retained in the indcnturcs or advantages to pockets formed in the plate mcmher will he' spilled from the plate member and only those washers that are retained in the pockets will remain on the plate. ll it he desired to assemble conical washers, the indentures or pockets may readily be so formed and dimen sioned' that only those ushers striking the plate with a predetermined side uppermost will be retained. By a further tilting or rotary motion ot' the plate the washers, held in the indentures are assembled or strung on a wire having an impaling device on its lower end that prevents release of the washers after they are once threaded on the wire. I A Washer sorting or stringing machine constructed in accordance with my invention I is illustrated in Fig. 1 of the drawing, where- .than would otherwise result.

in a. hopper 10 is adapted to receive a supply of loose washers 11, that are intermittently delivered to a select 18, a few at a time, by a distributor roll 12, having a pocket 13 formed in its face. Rotation of the roll. 12, which is rotated by the driving disc M, distributes a few of the washers to a lo..... portion 15 of the hopper which guides tl washers to a discharge device vice consists of an aperture formed between a swingahle plate 17 and the lower portion of the hopper The sWingahl-e plate ten, to arrange the washers so that they will drop flatly upon the plate 15% and roll on edge thereorer utter being rep 're-zl from the hopper.

The selector plate 18 ported on a crank arm 19 to cillatory motion about a pivotal axis "all. A. link 21 connects the outer end the crank arm to a crank pin 22 formed on the driving disc 14:. The two extreme positions for the selector plate 18 are respectively shown in solid and dotted outline in Fig. 1. The movement from one extreme position to the other is'accomplished by a pivotal or rotative motion about the axis 20 as a center.

The selector plate 125 has a series of pockets or indentures 24: of theshapc of the washers to he strung, formed in the plate near its outermost edge portion. If conical washers are to he strung, the indentnres are formed with sloping side Walls, as indicated inthe drawings, in order to retain the washers with their flat side uppermost. Each of these indcnlurcs communimlcs with an aperture 5 that extends completely through the plate for the reception of the tips 01' stringing wires 26 as hereinafter set "forth. The indentui'es 2% are separated from one another by haille plates 27 that extend longitudinally of the. plate and that serve to distrilnlte evenly the washers over the selector plate. v

A ridge 28 that, extends across the toe of the plate presents means for retarding the flow 'ot washers in the'vicinity of the indentures 2 thereby causing a greater percentage of washers to be retained by the indentures .l ig. 2 is a lateral sectional view ofthe toe of the selector plate, taken through the lineot' selector pockets.

A series of stringing wires 26 are removably supported from a bracket- .29 by set llll i or blocks 31 in their proper relative posiscrews 30, each of which is mounted in a block 31. The lower end of-each of the wires has a spring point 32 that prevents release of a washer after it is once impaled on the wire. Two sets of guide rollers 33 and 34: 1 iaint tin the tips 32 of the wires in registered alignment with the pockets of the selector plate when it is in its uppermost position, indicated by the broken lines. Fig. 3 illustrates the appearance of each of the sets oil guide rolls as viewed from above.

,The upper portion of each of the string ing wires 26 has a spring 35 mounted conceiitrically with it that seats against the bracket 2i) at its upper-end and against an adjustable sleeve 36 at its lower end. a The sleeve 36 is clamped upon the wire by means of a screw 37.

The upper end of each of the wires is secured in one of the blocks 31, which are individually free to rise and fall with any vertical movement of the stringing wire, such, for instance, as would result if the wire became entirely loaded with washers and were not removed from the machine.

A pair (it guide pins 38 maintain the weights tions.

The operation of my machine may best he described by tracing the steps in the treatment of a small group of washers from the time they leave the hopper to the time they are strung upon one of the wires 26. Vi ashers l] are poured into the hopper l() and are intermittently carried a few at a time into the lower port on of the hopper by means of the distributor roll 12. When the washers reach the discharging orifice of the hopper the swingable plate 17 engages and causes each of the washers to lie flat against the side of the hopper, thereby causing each of the washers to drop with one or the other of its faces against the selector plate 18 instead of dropping on edge on the inclined plate, which would cause the washers to roll oil the inclined plate without being caught by it.

The motion of selector plate 18 is so timed in its operation with respect to the distributor roll 12 that the washers are dropped on to the plate when it is substantially in the position shown in solid, out-' line in the drawing. The inclination of the distributor plate permits the Washers to slide down to the toe of the plate and,since certain of the washers will drop with the convex side down, these washers will be caught in the selector pockets 24, which fit the convex rather than the concave side of the washer. When the selector plate is operated about a pivotal center 20, through the agency of the crank arm 19 and the link connection 21, to the position shown in broken lines in the drawing, the washers that are not retained in the selector pockets 24 of the plate will be spilled oil the haclr oi the plate, thereby freeing the plate from washers that are not retained in the selector pockets.

As the selector plate 18 advances toward its uppermost'position, as indicated in broken lines in the drawing, the spring point 32 ot the corresponding stringing wire 26 registers with the openin in the washer retained in the selector p'ochet and the continued upward movement of the selector plate forces the washer over the spring point upon the wire.

This process is repeated until a complete string of'washers are threaded upon etch ot' the stringing wires 26. When any one of the stringing wires is completely loaded withwashers, the continued operation of the selector plate merely lifts the wire against the action of the spring and of the corresponding block 31, one of which is attached to the top of each of the respective wires. It will, therefore, be seen that there is no danger of bending the stringing wires by mechanically crushing them against the top of the machine, since the spring points at thechottorn ofeach of the wires become ineffective after the wire is completely loaded with washers.
